Conservation agriculture is often perceived to provide “win-win” outcomes for farmers leading to reduced erosion and off-site sedimentation, as well as improved soil fertility and productivity. However, adoption rates for conservation agriculture in many regions of the world remain below...

Litchi is an important crop in the mountainous part of northern Thailand yet its profitability has declined during the last 15 years. The replacement of litchi fruit orchards for seasonal flowers and vegetables has external costs related to increased levels of soil erosion, pesticides, and...

In face of climate change and other environmental challenges, inclusion of perennial forage shrubs in Australian agricultural systems has the potential to deliver multiple benefits: increased whole-farm profitability and improved natural resource management. The profitability of shrubs was...

For applications in agricultural economics, complex ecological systems are often oversimplified to the extent that ecologists rarely consider model results valid. Recursive optimization of complex systems represents an alternative, but requires strong assumptions regarding time preference and...

Payment for environmental services (PES) is a promising mechanism for conservation. It also has the potential to contribute to social objectives such as poverty reduction. To promote synergy in the implementation of PES, however, a number of conditions on spatial, economic, ecological, and...

This paper addresses the question of summer cover crop adoption by farmers in presence of a risk of yield loss due to take-all disease and climate variability. To analyse the public incentives needed to encourage farmers to adopt summer cover crops as a means of reducing N leaching, we combine...

Spain is the most arid country in Europe and water use as well as water depletion and environmental degradation have slowly become a matter of social concern. Balancing the two objectives of “water for rural livelihoods” and “water for nature” constitutes a difficult challenge for the...

Based on the “growth drag” conceptual model of Romer, this paper computes the growth drag of water resource on agricultural development through using panel data(1997～2006) of China’s all provinces. The result shows the growth rate of agricultural production value fell 0.1121% per year on...

Global efforts to reduce deforestation rely heavily on protected areas and land use restrictions. The effect of these restrictions on local communities is currently the subject of heated debate among conservation and development experts. Measuring the social impacts of protected areas is...
